Abstract
The utility model discloses a small-sized tweeter suitable for an electronic organ. The small-sized tweeter includes a cone frame, a magnetic conductive bowl fixed at the bottom of the cone frame, a magnet arranged at the center of the magnetic conductive bowl, a cone of which the periphery is fixedly connected with an opening of the cone frame, a voice coil which is formed through winding a wire on a cylindrical frame, a centering supporting sheet and a dustproof cover, wherein the cone is a curve cone, the dustproof cover is made of a polyester material. According to the small-sized tweeter suitable for the electronic organ, the curve cone is adopted to replace an existing liner cone, namely, the taper side surface of the cone is arc-shaped and protrudes inwards, and therefore, the height of the cone can be decreased with high sound quality ensured, and the overall height of the tweeter can be controlled under 16 mm; and the light cone and dustproof cover are adopted, the tweeter can have better timbre, and only 10DB unevenness exists in bandwidth from 3K to 15KHz, and the tweeter has 82.5DB sensitivity and can satisfy use requirements of the electronic organ.
Description
Technical field
The utility model relates to loud speaker field, particularly a kind of small-sized loudspeaker that is applicable to electronic organ.
Background technology
Loud speaker is a kind of very conventional electro-acoustic transducer device, Figure 1 shows that the basic structure schematic diagram of the coil-moving speaker of prior art.As shown in Figure 1, existing coil-moving speaker comprises taper basin frame 1, be fixedly installed the magnetic conductor bowl 3 of taper basin frame 1 bottom, be arranged on the magnet 2 of magnetic conductor bowl center, be arranged on the magnetic conductive board 4 at magnet 2 tops, the taper cone 5 that outer peripheral edges are fixedly connected with basin frame opening, described taper cone center is fixedly connected with cylindrical skeleton, on described cylindrical skeleton, be wound around and form voice coil loudspeaker voice coil 7 by a wire, also comprise outer end and the inner centring disk 6 that is fixedly connected with basin frame and cylindrical skeleton respectively and can spacing described cylindrical skeleton moves both vertically up and down simultaneously, wherein, between described magnetic conductive board and magnetic conductor bowl, form the uniform magnetic gap of a circle, the winding part of voice coil loudspeaker voice coil is symmetrical in magnetic gap and arranges.
When moving-coil speaker work, the wire of voice coil loudspeaker voice coil winding has electric current to pass through, and according to left hand rule, the winding in magnetic gap can produce the power conforming to direction with the current strength of flowing through and promote cone motion.Because centring disk and cone are movabilities on the direction of vibration of cone, but have very large rigidity in the direction vertical with direction of vibration, ensure voice coil loudspeaker voice coil winding part can be in magnetic gap proper motion and deflection does not occur.
Electronic organ is a kind of keyboard instrument, and it adopts large scale integrated circuit, mostly configure sound mnemonic (wave table).For depositing the actual sound waveform of each kind musical instrument and output in playing, the sound of output require loudspeaker to realize, because as musical instrument, mention and the tonequality of loudspeaker are received strict requirement, and this just needs a kind of novel loudspeaker that are applicable to electronic organ.
Utility model content
Technical purpose of the present utility model is the shortcoming that overcomes prior art, and a kind of small-sized loudspeaker that is applicable to electronic organ is provided.
For realizing above-mentioned technical purpose, the technical scheme that the utility model adopts is:
A kind of small-sized loudspeaker that is applicable to electronic organ, comprise basin frame, be fixedly installed the cone that magnetic conductor bowl, the magnet that is arranged on magnetic conductor bowl center, the outer peripheral edges of basin frame bottom are fixedly connected with basin frame opening, be wrapped in by a wire voice coil loudspeaker voice coil forming on cylindrical skeleton, centring disk, and dust cover, wherein, described cone is curve basin, and shown dust cover is terylene material.
Described cone height is 7mm, and upper end open diameter is 40mm, and the radius of curvature of described cone is 50mm.
Described dust cover is that 0.05mm-0.07mm is thick, and shown cone weight is at 0.6-0.8g.
Described basin frame both sides have formed engaging lug, on described engaging lug, are formed with connecting hole.
On described basin frame, be provided with two line holes, be fixedly installed connecting ear on described basin frame, the wire two ends of described voice coil loudspeaker voice coil are worn respectively cable-through hole and are connected with connecting ear simultaneously.
With respect to prior art, the beneficial effects of the utility model:
The utility model adopts the curve basin straight line basin before substituting, and the cone flank face of cone is circular arc and caves inward, and the height that it has reduced cone under the prerequisite that ensures high tone quality, can be controlled at the whole height of loudspeaker below 16mm.Meanwhile, adopt lightweight and cone and dust cover, make it have better tone color, in the frequency range of 3k-15KHz, only have the unevenness of 10DB, there is the sensitivity of 82.5DB, meet the user demand of electronic organ.
